VENETIAN BLIND BRACKET Filed Feb. 15, 1936 Patented Oct. 13, 1936 UNITED STATES PATENT OFFICE VENETIAN BLIND BRACKET corporation of Ohio Application February 15, 1936, Serial No. 64,018

' 6 Claims. (01. 156-17) This invention relates to Venetian blinds and more specifically to means for removably supporting and actuating the tilt rail, and which will permit the blind to be easily and quickly removed from and/or replaced in the supporting brackets without disturbing or disconnecting the actuating parts, thus rendering the cleaning, dusting, removing, and replacing of the blind a simple and easy operation.

A further object is to design a simple, practical, and economical Venetian blind bracket and actuating mechanism which is of rugged and substantial construction, and which when mounted is securely locked in position, eliminating the possibility of disconnections from bouncing which is caused by jerky and violent operation of the blind.

Another object of the invention is to provide a tilt rail bracket and actuating mechanism which is removable as a unit with the tilt rail, which is smooth and easy in operation, and which is economical to manufacture and assemble.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawing, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion, and minor details of construction, without departing from the spirit, or sacrificing any of the advantages of the invention.

In the drawing- Fig. 1 is a fragmentary front elevational view of a Venetian blind.

Fig. 2 is an enlarged detail front elevational v1ew.

Fig. 3 is an end elevation view of the structure shown in Fig. 2.

Fig. 4 is an end view of the bracket on the opposite end of the tilt rail illustrating the locking dog, the broken lines showing the dog swung up to permit removal of the tilt rail.

Fig. 5 is an enlarged sectional view showing the bracket actuating mechanism, and tilt rail clip.

Fig. 6 is a detail end View, the clip and worm Wheel being omitted.

Fig. '7 is a view similar to Fig. 3and showing an alternate construction.

The conventional Venetian blind comprises a head rail I which is mounted in the window opening H in any approved manner; brackets l2 and [3 respectively are secured to and depend from this head rail and are adapted to pivotally support a tilt rail 14 as usual; spaced apart ladder tapes I are attached to and hang from opposite edges of the tilt rail and serve to support a plurality of slats IS in the conventional manner, and by tilting the tilt rail any desired adjustment of the slats can be obtained.

The general operation of a Venetian blind is well known, and it is not deemed necessary to describe it in detail, as this invention is directed to the brackets and associated actuating mechanism which support and control the pivotal movement of the tilt rail, and the description will, therefore, be limited to this combination.

The tilt rail proper is of the usual construction, and preferably metal clips l1 and I8 respectively p are secured to the ends thereof, a pin or gudgeon l9 projecting from the .clip I8 and is adapted to be mounted in a slotted passage provided in the bracket l3, said passage being slightly inclined, and a locking dog 2| is pivotally mounted on the bracket, the hook-shaped end 22 forming a closure for the passage and locking the pin in position.

A clip I! is of similar construction and is securely mounted on the opposite end of the tilt rail, a worm wheel 23 being mounted on said clip and forming an extension of the tilt rail, said worm wheel being formed with a hub 24 which terminates in a reduced threaded section 25 on which a nut 26 is threaded as usual.

The worm wheel meshes with and is adapted to be driven by a worm 2! which is mounted in suitable bearings provided in the housing 28, a sheave 29 being mounted on the outer end of the worm shaft, and a cord 30 is trained over said sheave so that the mechanism may be actuated. A suitable bearing 3| is provided in the end wall of the housing 28, and the hub 24 is journaled therein, the nut 26 serving to hold the worm wheel and worm in assembled relation. An upwardly projecting flange 32 is formed integral with the housing, and laterally projecting lugs or pins 33 are formed integral therewith, said pins being accommodated in suitable openings 34 provided in the bracket l2, and While in the present instance I have shown these pins and openings to be round, it will be understood that they may be square or of any other desired shape. It will also be obvious that but one square or other shaped pin 35 may be utilized as shown in the modified construction in Fig. 7 of the drawing, and it will be further understood that the pins and openings can be in any desired angular relation, or that the bracket and housing flange may be so shaped as to form an interlocking engagement.

This arrangement permits easy and quick rethe removal of the nut 26 is all that is necessary.

From the foregoing description it will be obvious that I have perfected a very simple,' practical, and

inexpensive bracket and actuating mechanism for Venetian blinds.

What I claim is:

1. A Venetian blind including a bracket secured to a support and supporting one end of a tlltrall, a blind tilting mechanism and housingetherefor mounted on one end of the tilt rail, and means for securin said housing and tilt rail as aunit in detachable interlocking engagement with said bracket.

2. A Venetian blind including a bracket secured a to a support and supporting one end of a tilt rail, a-blind tilting mechanism and housing therefor mounted on one end of the tilt rail as a unit, and means on said housing for detachably securing said housing to said supporting bracket.

3. A Venetian blind including a depending bracket secured to a support and adapted to sup- 1 port one end of a tilt rail, a housing and tilting mechanism unit forming an extension of the tilt rail, and means for detachably securing said housing to said bracket.

4. A Venetian blind including a bracket secured to a support and adapted to support one end of a tilt rail, a Worm wheel fixed on one end of the tilt rail, a housing for said worm wheel secured to said rail, a worm mounted in the housing and meshing with said worm wheel, and means for detachably securing said housing to said bracket.

5. A Venetian blind including a bracket secured to a support and adapted to support one end of a tilt rail, a housing and blind tilting mechanism secured to and mounted on one end of'said tilt rail and forming a removable unit therewith, and

means for detachably and nonrotatably securing said unit to said bracket.

6. A Venetian blind including a bracket secured to a support and adapted to support one end of a tilt rail, a worm wheel mounted on one endof said tilt rail, a housing for said worm wheel secured to said rail, a worm journaled in the hous ing and meshing with said worm wheel, openings in said bracket, andpins on said housing and removably lnsertable in said openings to permit the removal of the tilt rail housing and actuating mechanism as a unit. 7
